The Thermal Conductivity of Metal Rod Apparatus is used to study steady-state heat conduction along a metallic rod. It allows measurement of temperature gradients and calculation of thermal conductivity. The setup includes a heater, cooling system, and thermocouples connected to a digital indicator. It helps students compare theoretical and experimental results. Designed for engineering colleges, polytechnic institutes, and ITIs, it provides a clear demonstration of conduction heat transfer in solids.
